Swedish company selling electric wheelbarrows.
The motor is inside the hub of the wheel and it has a great amount of torque. It'd be perfect for pulling things up that steep hill from the Waxholms dock! I could probably use it this weekend when I head out, loaded down with groceries. (Yes, that's right, this weekend! Yay!!)
If I lived there year around, it might be handy to have. But for my infrequent visits, it's better for me to get the exercise.
Their gallery of demonstration photos is quite amusing, it's worth a look.
